How To: Perform a Blackberry System Test
Woohoo for RIM having secret stuff in our OS and not telling us!!! Well I am spilling the beans. RIM has a secret little menu hiding inside your BlackBerry, as long as its running OS 4.2 or higher.
This little secret is a self diagnostic tool, which will help you figure out if something is wrong with your device.
To access this menu simply go options > status > then type the word test.
Once the application opens, click open your BB menu and click start.
Then simply check off the hardware you want to test.
This will be a handy tool if you need to check someones trackball/pad or other pieces of hardware.
